FD1182.DOC.001 V02.01.00 ® February 2025 6.2. Acuity tests visual 6.2.1. Purpose and presentation of the test The visual acuity test is the starting point of any eye examination. It ensures that a patient has the correct correction and assesses their ability to decipher information from everyday life. During an examination, we generally aim to achieve a visual acuity of 10/10, or even 12/10.
FD1182.DOC.001 V02.01.00 ® February 2025 6.2.3. Interface Description VisioWin® The visual acuity tests are split into as many vignettes as there are distance situations (near, intermediate, far) lighting (photopic/mesopic) to be tested.

FD1182.DOC.001 V02.01.00 ® February 2025 6.4. Astigmatism test 6.4.1. Purpose and presentation of the test This test is used to detect a defect of astigmatism in a patient. Astigmatism is due to a bad relationship between the power of the eye and its length. The vision of the astigmatic will then be distorted in a particular direction. If the astigmatism is too great, the patient will have poor acuity at all distances.

FD1182.DOC.001 V02.01.00 ® February 2025 The peripheral field is tested using 10 diodes per eye. They are arranged as follows: ✓ Nasal: 50° ✓ Temporal: 30°, 45°, 60°, 75°, 90° ✓ High: 22°, 30° ✓ Low: 22°, 30° The central field will test the central 30° of vision using 32 diodes per eye. They are arranged in the manner of an Esterman grid , which will give more importance to low vision as well as the horizon line.
FD1182.DOC.001 V02.01.00 ® February 2025 6.5.4.

FD1182.DOC.001 V02.01.00 ® February 2025 6.6. Relief test – Stereoscopy 6.6.1. Purpose and presentation of the test This test is useful to check the quality of stereoscopic vision which is essential for good binocular vision. It is this acuity which allows for depth vision and comparison of the proximity of objects between them. A problem with stereopsis can reveal certain disorders such as anisometropia , amblyopia, strabismus or image suppression problems.

FD1182.DOC.001 V02.01.00 ® February 2025 6.7. Phoria test 6.7.1. Purpose and presentation of the test The phoria test is used to highlight the tendency of an eye to deviate from its binocular fixation position in the absence of a fusional stimulus. We also speak of heterophorias or dissociated phorias, which are measured in prismatic diopters (∆).

FD1182.DOC.001 V02.01.00 ® February 2025 6.8. Fusion test 6.8.1. Purpose and presentation of the test The purpose of this test is to check the patient's binocular vision. It is known as the Worth test. It will allow us to know if the patient's brain is able to fuse the images from the right eye with those from the left eye. Fusion requires good visual acuity in each eye.
